Got the Zalman laptop cooler today, and was very excited especially since the expected delivery date was several weeks away! I had hummed and haahed about whether to buy directly from Amazon as it suggested a wait time of 1-2 months, so I am very happy that I did go with it. I had done a lot of research into laptop coolers, and this one seemed popular and well made, and at £12.50, a good option pricewise.

Huge box, but cooler inside is a normal size. It fits my Toshiba Satellite Pro well (17.3 " screen), although there is a slight overhang, this does not affect the cooling in the slightest.

I didn't find the usb cable a pain at all as I have a couple of sockets that can be used and the usb cable includes a socket of its own (so that you do not lose a socket effectively). The profile of the socket is a little larger than normal as a result, but should not cause you problems. The usb cable is located at the back of the unit in the middle, and so reaches either side of the laptop very easily.

This is a nice sturdy, attractive piece of equipment, the whole top surface is a metal mesh, so the fan air distribution is good all over. When on, it feels quite pleasantly cool. It is fairly quiet also (just a gentle whirr) and when you have anything with volume on your laptop, then you absolutely cannot hear the fan going at all. In fact, it is quite a lot quieter than the inbuilt laptop fan!

As for cooling, before I got this my laptop overheated very regularly whilst playing certain games. However much I underclocked the laptop, or hoisted it up to improve ventilation, the thermal indicator would run between 92C - 97C, and would often suddenly shut down when it exceeded that.Read more ›

I bought the Zalman ZM-NC3 and Targus Lap Chill Mat for Christmas. I gave the Targus to my girlfriend, and kept this one for myself.

We use the laptops in bed and on a duvet, for computer games, email etc. Sometimes the laptops got hot, especially on computer games - and possibly even affecting graphics performance if they overheat etc.

We've now used them for a month, and both are good. However, the Zalman is a more "closed-box" design, with the fan underneath. This doesn't work so well on duvets etc, as the fan gets blocked, and that makes it louder as it works harder. Even when lifted up, it still makes a whirring noise. However, it works and does keep the laptop cooler and my lap doesn't get hot anymore!

Comparing that to my girlfriend's Targus - hers is definitely better (and she won't swap). The Targus is an interesting, simple-looking "open-sided" design so air can get through the fans even on a duvet. Its also quieter (2 fans vs 1?). She was really pleased with the Targus, her laptop doesn't over-heat, its comfortable and she thinks the cooling has helped her graphics perform better.

So, I would be happy with the Zalman - but even happier with the Targus.

I bought this product on brand recognition as I had heard good things about Zalman cooling products.

The Laptop I am using this on currently is a Dell Vostro 1700 Laptop (17") and it fits on top very well.

The cooler is very quiet (not the quietest I have ever heard, but close, and far far quieter than when any Laptop fan spins / speeds up.

Edit: During the Heat Wave in the Summer (room around 30c) I choose to switch to my enormous (near £90 imported from France) Antec Gaming Cooler for .H264 encoding.This was because the heavy CPU usage for prolonged periods caused the Laptop fans to spin up and the Laptop got quite warm.This was never a problem, but as I had the Gaming Cooler thought I would use it.

So for Encoding or Gaming in a heat wave there are better coolers out there.

My Mum also bought one as well for her new 15.6" Samsung Core i5 Laptop.

Pros:1. Very quiet.2. Supports the Laptop well.3. Does a good job at keeping the Laptop cool.

Cons1. The USB pass through cable has the lead coming out of the side of the plug. Where this lead is positioned smaller laptops with side by side USB ports, will likely have either a port blocked by the lead, or the CD-DVD drive inaccessible as it gets in the way. (Solution use a USB extension cable, I had a small one I got with a flash stick.)

2. The position of the rubber feet on the cooler's surface.For smaller Laptops 15.6 inch and below they are not ideally placed, though have not tried to move these as they are screwed in, so maybe they can be moved.

I bought this to replace a worn out Logitech N100 and in my opinion, this isn't as good. It's not the quietest of coolers, despite having a large, slower moving fan and the noise either increases or decreases depending on the surface it is placed upon.

The plastic grill on the underside directly below the fan is quite flexible and can hit it if accidentally nudged for example, when using it perched on your lap. Due to the 'dished' design on the underside of the cooler and the position of the air intakes, it isn't very effective when used on a softer surface e.g. a cushion or duvet. I find the solution is to place a magazine underneath the cooler, which is a bit of a faff.

The size is good. It fits my 15.6in screen laptop perfectly and the rubberised mounts are quite useful. Whilst the combined USB fan connector / slot is handy in theory, for some reason my memory sticks don't like it and won't work.

The cooler seems quite well built and time will tell how long the fan unit will last.

In summary, a reasonable laptop cooler, especially for the price I paid (around £12) but if buying again, I'd go for one with a completely flat underside and air vents on the forward edge.
